Sports facility managers, sometimes called arena managers, stadium managers, general managers, or stadium operations executives, are responsible for the day-to-day operations involved in running a sports facility. They are involved in sports facility planning, including the buying, selling, or leasing of facilities; facility redesign and construction; and the supervision of sports facilities, including the structures and grounds, as well as the custodial crews. In 2015, the indoor sports facilities management industry consisted of more than 3,800 businesses and generated about $900 million in revenue, as reported by the market research group IBISWorld.
